ADUM2401BRIZ

Overview

The ADUM2401BRIZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 10 Mbps. The device provides 5000 Vrms isolation voltage with a common-mode transient immunity (CMTI) of 25 kV/µs. Key timing parameters include a maximum propagation delay of 50 ns, pulse width distortion of 3 ns, and rise/fall times of 2.5 ns. It functions in temperatures from -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates four independent bidirectional channels for high-density signal isolation
• Employs monolithic air gap technology for robust galvanic isolation without transformers
• Supports 3 V and 5 V logic level translation across isolated boundaries
• Provides high common-mode transient immunity for noise-sensitive environments

Applications

• Industrial automation control systems requiring multi-channel isolation
• Medical equipment signal interfaces demanding high safety isolation
• Power metering applications with multiple isolated communication lines
• Inverter gate drive circuits for motor control

Procurement Notes

Verify the specific suffix 'BRIZ' to confirm the tape-and-reel packaging variant and industrial temperature grade. Ensure compatibility with the 16-SOIC footprint during PCB layout. Confirm that the 10 Mbps data rate meets system requirements, as higher-speed variants exist within the family. Check moisture sensitivity levels for proper storage and reflow soldering profiles.

Selection Notes

Select this component when four isolated channels are required in a single package to save board space. It is suitable for designs needing 5000 Vrms basic isolation with moderate data speeds. Consider the 10 Mbps limit against faster alternatives if higher throughput is necessary. The wide operating temperature range makes it appropriate for harsh industrial or automotive-adjacent environments.

Part Context

This part belongs to the ADuM240x series of quad-channel digital isolators from Analog Devices. It shares the same core architecture as the ADUM2401ARIZ but differs in performance specifications and packaging options. The series represents a shift towards integrated magnetic coupling solutions replacing traditional optocouplers in multi-channel applications.

Replacement Considerations

The ADUM2401ARIZ is a parameter-equivalent alternative within the same product family. Verify pinout compatibility and ensure the replacement meets the specific insulation and CMTI requirements of the original design.
